I didn't describe him as a villain, he wasn't a mustache twirling megalomaniac... he was a self-involved douchebag who assisted in the downfall of humanity not of some malevolent plan... but because he wanted to get his dick wet.
I'd say that makes him pretty bad guy.
And they started the episode with it. No build up or plotting, just "Hey you know this strong independent women youre supposed to empathize with? We threw her in bed with the worst possible person we could create." That has all the subtlety of those screamy jump scare videos from the late 90s. Cheap and incredibly lazy, meant to invoke a strong reaction... not a meaningful one.
